Hi all,
a coaxial line EM discharger is not enough when a lightning arrive on your antenna. I had a 8 meters long vertical antenna on the top of the roof. It simply exploded, I found several parts of a coil meters and meters far away from the home.
I always disconnect all antennas from my radios. But that time it arrived on my antennas and damaged:
- the vertical antenna
- one power supply
- IC 7k and antenna tuner
- Kenwood TM702
- one computer
- adsl router
- voip gateway
- tv antenna amplifier
- water heater control board
- satellite tv feeder
- some parts of the roof.
So I bet that nothing can protect a radio in this condition. The electrical discharge found a privileged path throut the grounding wire of the power supply. I noted, in fact, the most of the damages are on components close to metal parts connected to ground.
In the IC 7k, some components on the RF board vaporized and on the lower metal panel there a huge sign of this explosion - I couls say the evidence of the electrical discharge.
So probably all of you are right, and I simply have to think if to look for spare parts or not.
Thank you again.
